Suppose that scores on a particular test are normallv distributed with a mean of 110 and a
standand deviation of 15 . What is the minimum score needed to be in the top 20% of the scores
on the test? Carry your intermediate computations to at least four decimal places, and round your
answer to one decimal place.
